Fixed use of old instances variable "@io_wait" (issue #341). Now the
default value for io_wait_timeout can be set correctly.

Fixed bug in announcer. It announces infomation several times due to
duplicate announce-calls.

Refactored internal #simple_table-method (internal)

Refactored announcer: Now it supports blocks for #announce as well (internal)
